So yes, in my view, that is both understandable and acceptable.

If the BA lounge was large enough to accommodate CX passengers, you can be certain that CX would choose to send its passengers there rather than in the SK lounge. They have looked at that less intuitive solution for a reason - namely that the BA lounges already get very full with the BA passengers alone even on 'average' days, let alone on very heavy business traffic days.
